<p>um, shoe size??? how do you think schools weight?</p>
<p>I don't know. Guidance doesn't know either. It's outsourced to a big company, and they put a lot of numbers into a machine and it spits out ranking. I think it uses weighted GPA, and counts lab courses 1.25. I don't know if it counts As differently from A+s. APs count the same as honors.</p>
